Redwatcher is a Reddit monitoring tool. Tracks keywords, brand mentions and competitors across the subreddits you choose, scores every match for relevance, and alerts by email, Slack, Telegram or webhook around the clock. From $29/month per project. A project is one brand or one client, with its own keywords, its own subreddits and its own alerts. A subreddit is one of Reddit's communities, each built around one topic. A keyword is a word or phrase you want found, a match is a Reddit post or comment that contains one, and a webhook is a message Redwatcher sends to a web address you give it. A relevance score is a number from 0 to 100 that Redwatcher gives each match, with the reasons, and you set the lowest score a thread needs before it is sent to you. A thread is a Reddit post together with the comments under it, so one thread can hold several matches, and a check is one pass in which Redwatcher reads your subreddits for new posts and comments.

Why do people look for a SubSignal alternative?
People look for a SubSignal alternative when 3 communities and 10 keywords on the $29.99 plan is too few, or when they want new threads in Slack, Telegram or a webhook. A community is SubSignal's word for a subreddit. SubSignal is a Reddit monitoring tool that, in its words, "watches every relevant thread, scores buying intent, and shows you exactly where to reply", and its Growth card lists "Email digests". Redwatcher reads the subreddits you choose around the clock, multiple times every hour, and sends the threads that reach the score you set to email, Slack, Telegram or a webhook on every plan.

What is SubSignal's pricing?
SubSignal costs $0 for Free, $29.99 a month for Growth and $129 a month for Professional, or $199 and $999 a year for Growth and Professional billed annually. It also sells ShillGuard, a $2.99 browser extension that checks Reddit accounts for bots and shills and does not monitor Reddit, and Kickstart, $15 once for 15 days of Growth. Growth has a 7-day free trial. Its cards count scans, AI insights and SEO opportunities a month without saying what one of each is, and its home page says the Sales Lead Finder finds posts asking for tools and "scores them by buying intent". Growth includes 500 credits a month for its API and its MCP server and Professional 10,000, without saying what one credit buys, and Free includes none. An MCP server lets AI assistants such as Claude and Cursor use a tool directly, and its card describes SubSignal's as "for Claude & Cursor". Read from subsignal.ai on 28 September 2026.
| Free | Growth | Professional | |
|---|---|---|---|
| Price, on subsignal.ai | $0 | $29.99 a month, or $199 a year | $129 a month, or $999 a year |
| Communities and keywords | 1 and 3 | 3 and 10 | 10 and 50 |
| Scans a month | 5 | 50 | 1,000 |
| AI insights a month | 5 | not stated | 100 |
| SEO opportunities a month | not included | 5 | 50 |
| "Monitor ALL of Reddit" | not included | included | included |
| Sales Lead Finder | not included | included | included |
| Email digests | not listed | included | included, because Professional has everything in Growth |
| API and MCP server credits a month | none | 500 | 10,000 |
| Reddit DM Automation | not included | not included | included |
The table leaves out ShillGuard, the one card of the four that is not a monitoring plan, and Kickstart, which is 15 days of Growth for $15 once. SubSignal's Growth card lists both 3 communities and "Monitor ALL of Reddit", and does not say how the two relate. Its FAQ says it does not "automate any interactions (no voting, posting, or commenting)", and its $129 Professional card lists "Reddit DM Automation", automated Reddit direct messages, which its FAQ says needs your own Reddit account connected.

SubSignal review: what does its $29.99 plan include for Reddit?
Three communities and 10 keywords, what its card calls "Monitor ALL of Reddit", 50 scans a month, 5 SEO opportunities a month, the Sales Lead Finder, email digests, and 500 credits a month for its API and its MCP server. Its home page says each post "gets a match score" by buying intent, and its FAQ says results can be exported to CSV. Read from subsignal.ai on 28 September 2026.
Why Redwatcher is the better SubSignal alternative for Reddit
- Twenty-five keywords in 25 subreddits for $29. SubSignal's $29.99 Growth plan covers 3 communities and 10 keywords. Redwatcher's $29 plan is 25 keywords in 25 subreddits you choose, its $49 plan is 50 of each, and no keyword is ever switched off.
- Sent to email, Slack, Telegram or a webhook. SubSignal's Growth card lists email digests. Redwatcher sends the threads that reach the score you set to email, Slack, Telegram and a webhook signed with a shared secret, on the $29 plan and on every other. Slack, Telegram and the webhook get one message per thread. Email gets one message per check, carrying the threads from that check.
- No charge per mention. Redwatcher costs the same however many threads it finds, and what you pay depends only on how many keywords and subreddits you watch. SubSignal's Growth card lists 50 scans a month and does not say what a scan is.
- The reason under every score, and when a score is wrong, you say what was wrong and it becomes a rule. SubSignal gives each post a match score. Under one Redwatcher thread the reason reads "A buying decision in progress, with the requirements and the budget stated", and that thread scores 94.
- Redwatcher never acts on Reddit for you. SubSignal's $129 plan includes Reddit DM automation. Redwatcher finds the thread, scores it, explains the score and links to it, and it never sends a message, a reply or a vote from your account.
Redwatcher watches Reddit only, has no free plan, and does not write or post replies. Read from subsignal.ai and redwatcher.com/pricing on 28 September 2026.
